In today’s convenience age when it comes to kitchen appliances, the art of coffee making is sometimes overlooked.
Many people will grab the pre-ground coffee from the grocery store, put it in a drip coffee maker, and voilà you have your coffee.
The problem is your not getting the best results, and more often than not we end up going to the coffee shop on our way to work weeks later for better coffee.
In this article, at Your Kitchen Zone, we’ll help you find the best coffee maker (with grinder) for you to help make that same cup of joe as you buy from coffee houses with huge savings in time and your wallet!
How can the best coffee grinder change the flavor of coffee?
To understand how grinders play a significant role in the flavor profile of your coffee you have to understand what exactly a coffee mill (another word for a grinder) does.
Now I am sure most of you are rolling your eyes right now because everyone knows that the best coffee grinder grinds down coffee beans, but we need to take a deep look into the process.
Why do we grind the beans in the first place?
If you look into the history of coffee, you will found out the first extraction of coffee beans was by agitating the bean through a long boiling process.
This process left you with a highly caffeinated, bitter, and thick concentrate of coffee.
Lucky for us we have since started grinding coffee and running water through the grounds.
Why? Well, coffee beans contain caffeine and oils inside of the bean.
These oils are what give coffee its aroma and taste and the caffeine well it’s what makes sure we get to work in a less zombie like state!
So why is it bad to buy pre-ground coffee?
Pre-Ground Coffee offers a host of issues:
- Oxidation – Most of the armor that we get from coffee is due to gasses trapped inside of the bean after roasting. The minute you grind the bean is introduced to Oxygen, and the gasses interact in what is called oxidation. After grinding coffee beans after 20 minutes, an estimate of 60% of the coffee aroma is released and gone. Simply put you lose most of your armor and some of your flavor profile from pre-ground coffee.
- Soluble Oils – Coffee bean oils are soluble. That is excellent news for us or else the brewing process would be much more challenging. The problem is when you grind coffee beans and expose them to the environment moister in the air starts to dilute these essential oils. That is why the best cups of joe are ground fresh and brewed as soon as possible.
- Delicate Oils – Coffee oils are very easily manipulated by their environment once they are out in the open i.e. they have been ground. They will often pick up and hold odors from around the grinds if exposed for extended periods of time. These new odors only weaken or sometimes even spoils the brew.
- Weakens the Roasting Process – During the roasting process, a lot of CO2 is created. Carbon dioxide is needed during the brewing process to help release the oils for a more flavorful and aromatic brew. When you grind your coffee, it creates more surface area in your beans raising the probably of release CO2. According to coffee confidential, almost 80% of all CO2 is released within 60 seconds after grinding.
Grinding Process- Types of Coffee Grinders
Knowing that the best cup of homemade coffee comes from freshly ground coffee beans lets look at how grinders work.
So there are two different type of mills, the first what we call the mini blender.
These mills use blades to grind up the coffee beans. They spin the blades as fast as the motors will allow it and the blade cuts where it hits the bean.
Two issues come from these little value beauties.
They are too inconsistent. Most of these grinders have only manual controls and grind meaning you control that grind. While controlling may sound like a good thing you are responsible for how long (how fine the grinds are) to let your blades run.
The process means its all on how long you run the grinder and well human error does occur. The other inconsistency is about the mechanism of the blades. Since the blades will be cutting the bean where ever it hits the bean, there is no consistency.
The second problem comes from the blade friction causing heat. With the blades swirling around and hitting solid objects friction heat starts to build up.
Remember those lovely oils we are trying so hard to preserve until we run the drip?
They don’t like heat especially after being ground up and out in the open. You lose a lot of the oils and moisture you with blade grinders; something grind fresh was supposed to preserve.
Burr grinders have two separate pieces commonly made of metal or ceramic that are set a specific distance apart (the size you want your grind).
The two parts then rotate and grind down the bean until it is small enough to fall through the opening leaving an ideal size of the bean.
To give you an idea this is the same concept used in pepper shakers that have mills in them. You turn the grinder and pepper fall out once it can fit through the burrs. There are two different types of burr mills flat plate and conical burrs.
There is a heated debate amongst coffee enthusiasts alike on which one of these kinds of burrs are better but almost everyone agrees that either is substantially better than a blade grinder and make the best coffee grinder.

|Medium||Size of Regular Sand||Flat-Bottom and Cone Drips|
|Medium Fine||Slightly finer than sand||Cone Shaped Poor Overs|

|Super Fine||Feels like flour||Turkish Coffee|
